Laser Cataract Surgery More Accurate Than Manual.
Cataract surgery, already an damned tried and true and winning procedure, can be made more critical by combining a laser and three-dimensional imaging, a revitalized study suggests. Researchers found that a femtosecond laser, occupied for many years in LASIK surgery, can cut dow a fell into delicate eye tissue more cleanly and accurately than guide cataract surgery, which is performed more than 1,5 million times each year in the United States buspar purchase. In the trend procedure, which has a 98 percent good rate, surgeons use a micro-blade to separated a around around the cornea before extracting the cataract with an ultrasound machine.
The laser custom uses optical coherence technology to customize each patient's visual acuity measurements before slicing through the lens capsule and cataract, though ultrasound is still Euphemistic pre-owned to take away the cataract itself. "It takes some adeptness and dynamism to break the lens with the ultrasound," explained conduct researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University vazox penis enlargement pills. "The laser helps to skedaddle this up and affirm it safer".
After practicing the laser plan on pig eyes and donated sensitive eyes, Palanker and his colleagues did further experiments to clinch that the high-powered, rapid-pulse laser would not cause retinal damage. Actual surgeries later performed on 50 patients between the ages of 55 and 80 showed that the laser jibe circles in lens capsules 12 times more faithful than those achieved by the ritual method. No adverse clobber were reported.
The study, reported in the Nov 17, 2010 emanate of Science Translational Medicine, was funded by OpticaMedica Corp of Santa Clara, Calif, in which Palanker has an tolerance stake. The results are being reviewed by the US Food and Drug Administration, while the laser technology, which is being developed by several exclusive companies, is expected to be released worldwide in 2011.

Acupuncture Can Treat Some Types Of Amblyopia
Acupuncture Can Treat Some Types Of Amblyopia.
Acupuncture may be an serviceable situation to behave older children struggling with a particular form of lazy eye, green research from China suggests, although experts reply more studies are needed. Lazy eye (amblyopia) is essentially a land of miscommunication between the brain and the eyes, resulting in the favoring of one affection over the other, according to the National Eye Institute. The go into authors acclaimed that anywhere from less than 1 percent to 5 percent of proletariat worldwide are affected with the condition . Of those, between one third and one half have a genus of sluggish eye known as anisometropia, which is caused by a rest in the degree of nearsightedness or farsightedness between the two eyes.
Standard care for children involves eyeglasses or in lens designed to correct zero in issues. However, while this approach is often successful in younger children (between the ages of 3 and 7), it is lucky middle only about a third of older children (between the ages of 7 and 12) Human Euphoria Cologne. For the latter group, doctors will often see a snippet over the "good" knowledge temporarily in addition to eyeglasses, and curing success is typically achieved in two-thirds of cases.
Children, however, often have tormenter adhering to revamp therapy, the treatment can bring emotional issues for some and a backward form of lazy eye can also plagiarize root, the researchers said. Study father Dr Dennis SC Lam, from the segment of ophthalmology and visual sciences and Institute of Chinese Medicine at the Joint Shantou International Eye Center of Shantou University and Chinese University of Hong Kong, and his colleagues discharge their observations in the December emerge of the Archives of Ophthalmology.
In the examination for a better way out than plot therapy, Lam and his associates set out to search the potential benefits of acupuncture, noting that it has been cast-off to treat dry eye and myopia. Between 2007 and 2009, Lam and his colleagues recruited 88 children between the ages of 7 and 12 who had been diagnosed with anisometropia.
About half the children were treated five times a week with acupuncture, targeting five circumscribed acupuncture needle insertion points (located at the superior of the run and the eyebrow region, as well as the legs and hands). The other half were given two hours a date of piece therapy, combined with a least of one hour per heyday of near-vision exercises such as reading.
After about four months of treatment, the inspection party found that overall visual acuity improved markedly more amidst the acupuncture order pertinent to the ground group. In fact, they eminent that while lazy eye was successfully treated in nearly 42 percent of the acupuncture patients, that calculate dropped to less than 17 percent surrounded by the patch up patients.
